Expression control – Layer Control

[Walter Soyka]

[Tiago Cav] “Could you teach me how to change for that the expression follow a specific layer, regardless of the index position between the layers within the Comp.”

This expression already does follow a specific layer. It just uses index as a test — is the index of the chosen layer my index? The index updates as you add, remove or rearrange layers.

I want to change the opacity of a layer, every time another layer (“text”) is selected in the “Layer Control”.

if (thisComp.layer("Control").effect("Layer Control")("Layer").name == "text") 100 else 0
